Excluding Networks Used To Back Up

Applies to:
  • CrashPlan PRO
  • CrashPlan PROe

Overview

The CrashPlan app allows you to exclude network adapters and wireless networks from use by CrashPlan. For example, this is useful if you want to prevent CrashPlan from:

  • Using a slow VPN connection
  • Backing up through a data card that could result in overage charges from your wireless carrier

This tutorial provides a step-by-step guide to excluding network adapters and wireless networks.

Excluding Network Interfaces

(Windows and OS X only)

With the network interfaces configuration, you can prevent CrashPlan from using specified wired connections. 

Steps

  1. Open the CrashPlan app.
  2. Go to Settings > Network.
  3. From Network interfaces, click Configure.

Network Settings

  1. Uncheck network interfaces that you do not want CrashPlan to use.

Excluding Wireless Networks

(Windows and OS X only)

Similar to the network interfaces configuration, you can prevent CrashPlan from using specified wireless networks (e.g. a mobile wireless hotspot with a usage cap). 

Steps

  1. Open the CrashPlan app.
  2. Go to Settings > Network.
  3. From Wireless interfaces, click Configure.
  4. Uncheck each wireless network that you do not want CrashPlan to use.

Changing The Network Interface Used For Backup

If you have multiple active network interfaces, CrashPlan will use the primary network interface assigned by your operating system. Like most applications, CrashPlan relies on the operating system to choose the interface it uses. If the primary interface is blocked, the CrashPlan app will block your connection, even if other network interfaces are available.

Network exclusions in CrashPlan work as follows:

  1. CrashPlan asks the operating system to make a network connection to the Code42 servers.
  2. The computer uses the interface that is listed by the operating system as the primary network interface.
  3. CrashPlan tries to use this connection to back up.
  4. CrashPlan checks its list of network exclusions. If the connection is excluded, it blocks the connection, and displays the message: Backup paused--network blocked.
